In the procession of runners weaving their way through the capital from Greenwich and Blackheath in south-east London to Buckingham Palace was Buster Martin.

At 101, the smoker, drinker and father of 17 is hoping to become the oldest person to complete the race. (BBC news)

Charming to see an elderly at 101 years old running a marathon! Mr Buster Martin looks so youthful!

Marathon running is not easy. The runner has to plan and discipline for a period of time to prepare and build up oneself physically and mentally.

One needs the stamina and persistence as virtually at different points of the stretch run, one would feel one cannot go on but when one mustered up courage and persists, one just breaks through to new lease of energies and strength and experiences joy.
